Sakai Community Practices: current 2.1.x "maintenance branch" is only meant for bug fixes
as of October 31, 2006, we are still putting in patches that have been tested locally
after we complete this step, we will start adding patches that have not been tested locally; at that time, 2.1.x will cease to be reliable
once we start committing patches that haven't been tested, we will probably need to move to a system where we add patches until a certain time, test until a certain time, and then release everything that passed as a new 2.1 tag
that timeframe may be something like weekly, biweekly, or monthly, depending on what the community decides
